CC -!- FUNCTION: This protein promotes the GTP-dependent binding of CC aminoacyl-tRNA to the A-site of ribosomes during protein CC biosynthesis. CC -!- FUNCTION: May play an important regulatory role in cell growth and CC in the bacterial response to nutrient deprivation. CC -!- FUNCTION: In case of infection by bacteriophage Qbeta, part of the CC viral RNA-dependent RNA polymerase complex. With EF-Ts may provide CC a stabilizing scaffold for the beta (catalytic) subunit. Helps CC separate the double-stranded RNA of the template and growing RNA CC during elongation (PubMed:22245970). With the beta subunit helps CC form the exit tunnel for template RNA. The GTPase activity of this CC subunit is not required for viral RNA replication CC (PubMed:20798060). {ECO:0000269|PubMed:20534494, CC ECO:0000269|PubMed:20798060, ECO:0000269|PubMed:22245970, CC ECO:0000269|PubMed:22884418, ECO:0000269|PubMed:25122749, CC ECO:0000269|PubMed:816798}. CC -!- FUNCTION: Plays a stimulatory role in trans-translation, binds CC tmRNA. {ECO:0000269|PubMed:15069072}. CC -!- SUBUNIT: Monomer. In case of infection by bacteriophage Qbeta, CC part of the viral RNA-dependent RNA polymerase complex, the other CC subunits are the viral replicase catalytic subunit (AC P14647), CC host ribosomal protein S1 and EF-Ts (PubMed:816798).

CC -!- SUBCELLULAR LOCATION: Cytoplasm. Cell inner membrane; Peripheral CC membrane protein. Note=Between 50-80% of the protein is associated CC with the cell inner membrane. Localization to the membrane has CC been suggested to follow nutrient stress. CC -!- PTM: The N-terminus is blocked. CC -!- PTM: Methylated in vivo on Lys-57 in response to nutrient CC starvation. {ECO:0000269|PubMed:2022614, CC ECO:0000269|PubMed:389663, ECO:0000269|PubMed:6997043, CC ECO:0000269|PubMed:7021545}.

CC -!- PTM: Phosphorylated in vitro by HipA on Thr-383 (PubMed:19150849), CC this has since been reported not to occur in vivo CC (PubMed:24095282). {ECO:0000269|PubMed:19150849, CC ECO:0000269|PubMed:24095282, ECO:0000269|PubMed:24141193, CC ECO:0000269|PubMed:8416965}. CC -!- MISCELLANEOUS: In order to produce high amounts of bacteriophage CC Qbeta RNA polymerase catalytic core, a fusion protein consisting CC of tsf-tufB-replicase with a cleavable linker between tufB and the CC viral replicase subunit is frequently used. CC {ECO:0000269|PubMed:16781472, ECO:0000269|PubMed:20798060, CC ECO:0000269|PubMed:22245970, ECO:0000269|PubMed:22884418, CC ECO:0000269|PubMed:25122749}. CC -!- MISCELLANEOUS: Present with about 70,000 molecules/cell. CC {ECO:0000305|PubMed:775340}. CC -!- MISCELLANEOUS: The antibiotic kirromycin inhibits protein CC biosynthesis by inhibiting the release of EF-Tu from the ribosome. CC TufA resistance to kirromycin is conferred by mutations to Gln- CC 125, Gly-317 and Ala-376. This has not been formally proven for CC tufB, but is certainly correct. {ECO:0000305}. CC -!- MISCELLANEOUS: The antibiotic pulvomycin inhibits protein CC biosynthesis by disrupting the allosteric control mechanism of EF- CC Tu TufA resistance to pulvomycin is conferred by Arg-231, Arg-334 CC and Thr-335. This has not been formally proven for tufB, but is CC certainly correct. {ECO:0000305}. CC -!- SIMILARITY: Belongs to the TRAFAC class translation factor GTPase CC superfamily. Classic translation factor GTPase family. EF-Tu/EF-1A CC subfamily. {ECO:0000255|HAMAP-Rule:MF_00118}. CC -!- CAUTION: EF-Tu 1 and EF-Tu 2 differ in a single position and are CC no longer merged. However, many papers are found in both entries CC as it is not always possible to determine for each paper which of CC EF-Tu 1 or EF-Tu 2 was being worked upon. {ECO:0000305}.
